Global quantum hardware companies as of December 2025

Welcome back to the Qubit Value Podcast! In our second episode of Season 3, we dive into the staggering advances in quantum hardware, where the industry has moved far beyond simple experimentation into the era of fault-tolerant systems.

Join us as we survey the leading contenders in the quantum race, exploring how giants like IBM and Google are competing with specialized innovators like QuEra and Xanadu. We break down the massive scaling achievements of IBM’s 4,000-qubit "Kookaburra" system and Atom Computing’s 1,000-atom arrays, contrasting them with the high-fidelity approach of Google’s "Willow" chip and Quantinuum’s breakthrough in creating reliable logical qubits. From the photonic strategies of PsiQuantum to Microsoft’s engineering of topological qubits, we examine why the industry’s focus has decisively shifted from raw qubit counts to real-time error correction and engineering reliability.
